The Effects of Ramadan-Fasting (RF) on Inflammatory and Hematological Indices of Stable Chronic Obstructive Pulmonary Disease (COPD) Male Patients: A Pilot Study

Chronic Obstructive Pulmonary Disease: The Role of Healthy and Unhealthy Dietary Patterns-A Comprehensive Review

Chronic obstructive pulmonary disease (COPD) is a progressive and irreversible disease affecting many people worldwide. Recent evidence suggests that diet and lifestyle play a vital role in COPD progression. We aimed to provide a comprehensive review of the effect of healthy and unhealthy dietary patterns on preventing and treating COPD. For this reason, Scopus, EMBASE, Web of Science, and PubMed were searched. Based on our findings, it appears that adhering to a healthy dietary pattern rich in vegetables, legumes, fruit, nuts, and whole grains may have advantageous impacts on preventing and treating COPD while following an unhealthy dietary pattern rich in red and processed meat, saturated fats, sweets, and sugary drinks affect COPD negatively. Adhering to Mediterranean, dietary approaches to stop hypertension (DASH), Prudent, Ketogenic, and High-protein diet may be related to a lower risk of COPD and improved pulmonary function. Conversely, Western and Ramadan Intermittent Fasting diets may elevate the prevalence of COPD. Proposing a nutritious diet that enhances pulmonary function could potentially be an effective approach to preventing and managing COPD. A comprehensive knowledge of the relationship between dietary factors and COPD can provide healthcare professionals with properly supported approaches to advise patients and empower individuals to make informed lifestyle decisions that are beneficial to improve their pulmonary health.

Patient Care During Ramadan: A Narrative Review

Ramadan is the Islamic holy month when Muslims around the world fast from dawn to sunset. This 30-day pattern of intermittent diurnal fasting can have a significant physiologic impact on the body. Importantly, oral intake is forbidden during this time, and many patients do not wish to take medications. From a clinical perspective, this potentially impacts healthcare delivery and chronic disease states. Despite these important changes, awareness of individual patient practices remains limited among healthcare providers in North America, which may worsen health disparities in Muslim patients. A fundamental understanding of the cultural and physiological implications of fasting during Ramadan can improve cultural competence and patient outcomes. In this paper, we review the physiologic changes during fasting, medical exemptions to fasting, and special considerations for the care of Muslim patients with chronic conditions who may fast during Ramadan.

The relationship between anemia and hyperuricemia and hypertension in Korean adults: the Korea National Health and Nutrition Examination Survey 2016-2018

OBJECTIVE

It is unclear whether uric acid (UA) has a negative or positive effect on anemia, and this may vary depending on the presence or absence of chronic disease such as hypertension (HTN). The present study was conducted to assess the relationship between anemia and hyperuricemia in Korean adults with or without hypertension.

METHODS

Data from 16,740 adults (age ≥20 years) in the Korean National Health and Nutrition Examination Survey (2016 - 2018) were analyzed.

RESULTS

Several key findings were identified. First, after adjusting for the related variables in the non-HTN group, the odds ratio (OR) of anemia (hemoglobin [Hb] ≥ 13.0 mg/dL in men and ≥12.0 mg/dL in women), using the normouricemia (UA < 7.0 mg/dL in men and UA < 6.0 mg/dL in women) as a reference, was inversely significant for the hyperuricemia (UA ≥ 7.0 mg/dL in men and ≥6.0 mg/dL in women) in the overall population (OR, 0.589; 95% confidence interval [CI], 0.409-0.848) and women (OR, 0.575; 95% CI, 0.363-0.909) but not in men (OR, 0.836; 95% CI, 0.441-1.586). Second, after adjusting for the related variables in the HTN group, the OR of anemia, using the normouricemia as a reference, was positively significant for the hyperuricemia in the overall population (OR, 1.501; 95% CI, 1.167-1.930), men (OR, 1.706; 95% CI, 1.154-2.523), and women (OR, 1.512; 95% CI, 1.079-2.210).

CONCLUSIONS

Hyperuricemia was positively associated with anemia in men and women with HTN. Hyperuricemia was inversely associated with anemia in women without HTN but not in men without HTN.

Effects of Ramadan Intermittent Fasting on the Severity of β-Thalassemia Major Patients

BACKGROUND

β-thalassemia major (β-TM) is an inherited autosomal recessive disorder manifested by the hemoglobin β chain synthesis alteration. It is a lifelong illness with a scope of a wide range of complications. Many kinds of literature evaluated the effect of Ramadan intermittent fasting (RIF) on different medical conditions. However, there are no precise guidelines regarding its effect on patients with β-TM.

METHODS

A retrospective cohort study was conducted on β-TM patients who visited the hereditary blood disorder center at Al Karama Teaching Hospital in Baghdad. Accordingly, six parameters were used to evaluate the effect of RIF on β-TM patients before, during, and after Ramadan. These parameters include hemoglobin level, frequency of transfusion, aspartate aminotransferase (AST) level, alanine aminotransferase (ALT) level, left ventricular ejection fraction % (EF%), and spleen size. All of these details, including the demographic characteristics of age, gender, history of splenectomy, and body mass index (BMI) were retrieved from the patient's medical records after confirming their fasting through one-to-one interviews. This study aimed to fill the gap and investigate the possible effect of RIF on the severity of β-TM.

RESULTS

A total of 184 β-TM patients were enrolled in this study. The mean duration of fasting was 25.2±2.18 days. More than half (110) of the patients were females (59.8%). Whereas, the mean age was 24.8±3.5 years. One-third of the patients (65) had a splenectomy (35.3%) and more than two-thirds had normal BMI. The initial parameters used to score the severity of β-TM were evaluated separately. As a result, the hemoglobin level remained steady without any statistical significance during the three months. In addition, the frequency of blood transfusion and the spleen size carried the same result. Although the lowest median and range of liver enzymes were recorded during Ramadan, they were statistically insignificant compared to pre and post-fasting. Moreover, the left ventricular EF% was insignificant regardless of the patient's history of heart disease.

CONCLUSION

This study revealed that RIF does not seem to affect the severity of β-TM if the patients proceed with fasting. However, further studies in more countries with a bigger sample size are recommended to confirm these findings.

Combined effect of gender differences and fatiguing task on postural balance, functional mobility and fall risk in adults with multiple sclerosis: A preliminary study

AIM

To investigate the gender difference effect on postural balance, functional mobility, and fall risk after performing a fatiguing task in adults with multiple sclerosis (MS).

METHODS

Eleven women (30.91 ± 8.19 years) and seven men (30.29 ± 7.99 years) with relapsing-remitting MS performed a fatiguing task: three sets of the Five-repetition Sit-To-Stand Test (5-STST) were performed before and after the six-minute WalkTest (6MWT). Bipedal postural balance in eyes open and eyes closed conditions were assessed prefatigue (T0) and postfatigue (T3) using a force platform. Unipedal balance, functional mobility (Timed Up and Go Test), fall risk (Four Square Step Test) and fatigue [Visual Analogue Scale of Fatigue (VASF)] were assessed at T0 and T3. Heart rate (HR) and Rating of Perceived Exertion (RPE) were recorded before (only for HR), during and after the fatiguing task.

RESULTS

Compared to women, men showed an impairment of posturographic parameters [mean center of pressure (CoP) velocity (CoPVm) in both conditions (p < 0.05); CoP sway area (CoPAr) in both conditions (p < 0.01)], unipedal balance on the dominant leg (p <0.001), mobility (p<0.001) and an increased fall risk (p < 0.05). No gender differences were observed in 6MWT, 5-STST, HR, RPE, and VASF.

CONCLUSION

This preliminary study showed that fatiguing task negatively affected postural control, mobility and fall risk only in men. These gender differences were inconclusive but could be taken into account in postural balance rehabilitation programs for MS persons.

Impact of Ramadan fasting on lipid profile and cardiovascular risk factors in patients with stable coronary artery disease

BACKGROUND

The effects of Ramadan fasting (RF) on cardiometabolic risk factors in patients with stable ischemic heart disease are not well known.

AIM

The aim of this study was to evaluate the impact of RF on lipid profile and cardiovascular risk factors in patients with a stable coronary heart disease.

METHODS

A prospective observational study carried out in the Cardiology department of Charles Nicolle Hospital (Tunisia). Eighty-four patients with a stable ischemic heart disease who intended to fast were enrolled during May 2020. Detailed clinical and biochemical assessments were performed before and after the holy month. Parameters of glycemic control, lipid profile, ultrasensitive C-reactive protein concentration (us-CRP) and homocysteine were performed before- and after- Ramadan (BR and AR, respectively).

RESULTS

Eighty-four patients including 79 males and 5 females, with a mean age of 57±7 years completed the study. Levels of cholesterol, triglycerides, low-density lipoprotein-cholesterol and apoprotein A were significantly improved AR fasting in comparison with their BR values. There was a significant decrease in blood fasting glucose, insulin level, Homeostasis model assessment of insulin resistance index and in us-CRP level.

CONCLUSION

In patients with stable ischemic heart disease, RF may be accompanied by an improvement of lipid profile and glycemic parameters without increase in coronary events.

[Applicability of the Arabic version of the French quality of life' (QOL) questionnaire (VQ11) in Tunisian patients with chronic obstructive pulmonary disease]

BACKGROUND

There is no validated Arabic version of the French questionnaire of quality of life, the VQ11. This study aimed to test the applicability of the Arabic version of the VQ11 in Tunisian patients with chronic obstructive pulmonary disease (COPD).

METHODS

It was a prospective and cross-sectional study, spread over seven months, that included 40 stable COPD male patients. The Arabic version of VQ11, translated by a bilingual expert, was used. The functional, psychological, relational and total scores were calculated. Patients were divided into two groups according to the GOLD classification: "A-B" (n=25) and "C-D" (n=15). A significant correlation-coefficient (r) of≥0.51, between the VQ11 total score and the ADO index (age, dyspnoea, obstruction), and higher quality of life scores in GOLD "C-D" when compared to GOLD "A-B" would be in favour of application of the Arabic version of the VQ11.

RESULTS

The mean±standard deviation of age, post-bronchodilator FEV₁/FVC, ADO index and VQ11 total score were 64±8 years, 0.55±0.08, 4.8±1.7 and 2±10, respectively. A significant "r" (0.56) was identified between the ADO index and the total score. Psychological, relational and total scores of GOLD "A-B" patients were significantly lower than those in GOLD "C-D" patients: 10±4 vs. 12±3, 11±4 vs. 13±3 and 30±11 vs. 36±7, respectively.

CONCLUSION

The Arabic version of VQ11 is applicable in Tunisian COPD patients with reliable results.

How to Stage Airflow Limitation in Stable Chronic Obstructive Pulmonary Disease Male Patients?

No study has evaluated the utility of different classifications of chronic obstructive pulmonary disease (COPD) airflow limitation (AFL) in terms of the refined “ABCD” classification of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) or in terms of the impacts on quality of life. This study aimed to compare some relevant health outcomes (i.e., GOLD classification and quality-of-life scores) between COPD patients having “light” and “severe” AFL according to five COPD AFL classifications. It was a cross-sectional prospective study including 55 stable COPD male patients. The COPD assessment test (CAT), the VQ11 quality-of-life questionnaire, a spirometry, and a bronchodilator test were performed. The patients were divided into GOLD “A/B” and “C/D.” The following five classifications of AFL severity, based on different post-bronchodilator forced expiratory volume in 1 s (FEV₁) expressions, were applied: FEV_1%pred: “light” (≥50), “severe” (<50); FEV_1z-score: “light” (≥−3), “severe” (<−3); FEV₁/height²: “light” (≥0.40), “severe” (<0.40); FEV₁/height³: “light” (≥0.29), “severe” (<0.29); and FEV_1Quotient: “light” (≥2.50), “severe” (<2.50). The percentages of the patients with “severe” AFL were significantly influenced by the applied classification of the AFL severity (89.1 [FEV_1z-score], 63.6 [FEV_1%pred], 41.8 [FEV₁/height³], 40.0 [FEV_1Quotient], and 25.4 [FEV₁/height²]; Cochrane test = 91.49, df = 4). The CAT and VQ11 scores were significantly different between the patients having “light” and “severe” AFL. In GOLD “C/D” patients, only the FEV_1Quotient was able to distinguish between the two AFL severities. To conclude, the five classifications of COPD AFL were not similar when compared with regard to some relevant health outcomes.

The Impacts of Ramadan Intermittent Fasting on Oxidant/Antioxidant Stress Biomarkers of Stable Chronic Obstructive Pulmonary Disease Male Patients

No prior study has evaluated the impacts of Ramadan intermittent fasting (RIF) on oxidant/antioxidant stress (OS/AOS) biomarkers in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess the impacts of RIF on some OS/AOS biomarkers measured in male patients with stable COPD. Fifteen COPD patients (mean age: 71 ± 6 years) fasting Ramadan in 2017 volunteered to take part in the study. Three sessions (before Ramadan [BR], end Ramadan [ER], after Ramadan [AR]) were selected. Blood samples of OS (homocysteine [μmol/L], thiobarbituric acid reactive substances [TBARS, μmol/L]) and AOS (catalase [U/ml], ceruloplasmin [g/L], superoxide dismutase [SOD, ng/ml], zinc [µmol/L], albumin [g/L]) biomarkers were consistently taken 4.5 to 2.5 hr before the iftar. Findings were analyzed by applying Friedman or Kruskal-Wallis ANOVA. Comparisons of the number of patients with high OS [high homocysteine and/or TBARS] and low AOS (low catalase and/or ceruloplasmin and/or SOD and/or zinc and/or albumin) blood values between the three sessions were performed using the Cochran test. The median ± interquartile of homocysteine (BR: 21.48 [18.98-24.49], ER: 23.15 [21.77-26.45], AR: 24.87 [21.91-37.12]), ceruloplasmin (BR: 0.27 [0.24-0.30], ER: 0.28 [0.26-0.33], AR: 0.28 [0.25-0.32]), SOD (BR: 288.00 [112.00-400.00], ER: 182.00 [152.00-386.00], AR: 234.00 [190.00-420.00]) and the mean ± SD of TBARS (BR: 5.66 ± 1.26, ER: 4.59 ± 0.78, AR: 5.29 ± 1.69), catalase (BR: 120.97 ± 54.62, ER: 106.73 ± 50.92, AR: 137.39 ± 40.88), zinc (BR: 11.85 ± 2.01, ER: 12.47 ± 2.34, AR: 12.21 ± 2.58) and albumin (BR: 39.78 ± 3.19, ER: 40.74 ± 2.26, AR: 40.56 ± 2.38) were not significantly affected by RIF. The number of patients with high OS (BR [ n = 13], ER [ n = 15], AR [ n = 14]) or low AOS (BR [ n = 12], ER [ n = 13], AR [ n = 13]) statuses were not significantly influenced by RIF. In conclusion, RIF did not induce any significant statistical or clinical changes in OS/AOS biomarkers or statuses in COPD patients.
